Abstract
The Transfer Matrix (TM) of an optical fiber characterizes the relationship between the input and output intensity and phase distribution. In this project we seek to measure the TM of Polarization Maintaining Fiber (PMF) in the basis of Linearly Polarized (LP) modes, which form a complete basis for supported inputs and outputs of the fiber. We investigate two methods for determining the TM. The first method is based on a genetic algorithm. The second method is to directly measure each individual matrix element of the TM. Using a spatial light modulator (SLM) we can control the input mode and characterize the Fourier coefficients of each supported mode at the output of the fiber.
